Answer:
Perimeter = 36cm
Step-by-step explanation:
The area of a square = l 2where l is the length of the square's side.
l 2 = 81 ⇒ l = √ 81 =9
hence Perimeter = 4 × 9 = 36 c m

One square has an area of 81cm². Calculate its perimeter.
[tex]\huge{ \mathfrak{ \underline{ Answer \: \: ✓ }}}[/tex]
For a Square,
[tex] \longrightarrow \: area = side {}^{2} [/tex]
[tex]side {}^{2} = 81[/tex][tex]side = \sqrt{81} [/tex][tex]side = 9[/tex]So, The measure of each side of the square is 9 cm

The faces of a fair 6 - sided cube are numbered 1 through 6. What is the probability that a 2 will land face up on the next roll? Give your answer as a fraction in simplest form and the percent.
Answer:
You will have a 1/6 probability of getting a 2 that will land face up on the next roll.
Step-by-step explanation:
There is only one two on the cube, which means you will have 1 chance out of 6 of getting a 2.

1. Predict the height ( in cm) of boy
who is 30 months old.
2. Predict the age of a boy who is approximately 115 cm tall.
Use the linear model equation y=0.58x+72.27.
Answer:
Step-by-step explanation:
It'd be wise to say what is represented by each x and y. I will assume that x represents the age of the child in months and y the height in cm.
Then, if the height is 115 cm, 115 cm = 0.58x + 72.27. Must solve this for x:
115 cm - 72.27 cm
x = ---------------------------- = 73.7 cm (about 29 inches, which is reasonable)
0.58
If the child is 30 months old, x = 30 and y (the height) is
0.58(30) + 72.27 cm = 89.7 cm (about 35.3 cm, also reasonable)

Jamie uses exactly 18 inches of dental floss every time she flosses her teeth. The package of dental floss she just bought contains 27 yards. How many times can Jamie floss her teeth with the amount of floss in this package?
Answer:
54 times
Step-by-step explanation:
36 inches = 1 yard
Since there are 27 yards, you multiply 36 by 27 = 972
If you use 18 inches each time, you would divide 972 by 18.
972/18= 54
So, Jamie could flow her teeth 54 times.

Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?
Answer:
18.4 cm²
Step-by-step explanation:
Una caja de carton se ha disenado para qu contenga 184cm cubicos. Si su altura es de 10cm, cual es el area de la base?
Volumen = Área de la base × Altura
Área de la base = Volumen / Altura
= 184 cm³ / 10 cm
Área de la base = 18.4 cm²
Por lo tanto, el área de la base es de 18.4 cm².

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!
Answer:
Volume, V = 3367.6 cm³
Step-by-step explanation:
Given the following data;
Diameter = 18.6 cm
Radius = diameter/2 = 18.6/2 = 9.3 cm
Pie, π = 3.14
To find the volume of the sphere;
Mathematically, the volume of a sphere is given by the formula;
[tex] Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3} [/tex]
Where;
r is the radius of the sphere.
Substituting into the formula, we have;
[tex] V = \frac {4}{3} * 3.14 * 9.3^{3} [/tex]
[tex] V = 4.186666667 * 804.357 [/tex]
Volume, V = 3367.6 cm³
Ellen has 20 feet of ribbon. She uses 12 feet of ribbon to make pillows. She gives one-fourth of the remaining ribbon to her friend. How many inches of ribbon did Ellen give to her friend?
Answer: 2 ft
Step-by-step explanation:
Given
Ellen has 20 ft of ribbon
She uses 12 ft of ribbon to make pillow
The amount of remaining ribbon is [tex]20-12=8\ ft[/tex]
She gives one-fourth of the remaining to her friend i.e
[tex]\Rightarrow \dfrac{1}{4}\times 8=2\ ft[/tex]
So, she give 2 ft of ribbon to her friend.

Rotate an isosceles right triangle around a line that contains the triangle's hypotenuse
Answer:
See attachment 2 for the rotation
Step-by-step explanation:
The question has a missing figure
See attachment 1 for the missing figure of the isosceles right-triangle
Required
Rotate around the hypotenuse
From the attachment, the hypotenuse is along the blue vertical line along the y-axis.
So, when the isosceles triangle is rotated around the hypotenuse, the result of the rotation we get a composite figure that has two congruent solids.
Which is a cone of radius and height equal to half of the hypotenuse
See attachment 2 for the rotation

Which of the following lines bets fits the data shown in the scatter plot?
write the product in standard form: (x+4)(x-4)
Answer:
x² - 16
Step-by-step explanation:
Use the FOIL method here where
F = first
O = outer
I = inner
L = last
F = x * x = x²
O = -4 * x = -4x
I = 4 * x = 4x
L = -4 * 4 = -16
Combine the terms to get x² - 16.
en las matematicas para que concepto se usan las letras?
Answer:
En matemáticas, las letras son utilizadas en las ecuaciones, para representar a través de ellas valores no conocidos que deben ser dilucidados por quien realiza la ecuación. Las letras más utilizadas con este propósito son las letras X e Y.
Así, por ejemplo, se da una suma con un valor numérico y un valor faltante denominado X, con un resultado también numérico, con lo cual el valor de X surgirá del resultado de la ecuación planteada. Por ejemplo:
8 + X = 10
X = 10 - 8
X = 2
8 + 2 = 10
